Specification of Letters Patent.

Patented July 422,/ 1919.

Application filed February 11, 1918. Serial No. 216,563.

To all whom t may concern: `i j i Be it known that I, EDsoN L. BnAnnsLnY, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Iiifters, of which the following is a specification.

rThis invention relates to lifters, and has for its primary object to provide a simple, adjustable and efficient tool for facilitating the removal of the valve structure found in internal combustion engines.

Another object of invention is to improve the construction disclosed in my former Patent No. 1,241,488, granted October 2, 1917, by rendering the construction disclosed in this patent adjustable, in order that the saine may be conveniently adapted for engines of various proportions or other structural differences.

A further object of the invention to provide lifter designed for use in assisting in removing the springs encircling the 4valve stems of, internal combustion engines. In grinding or replacing these internal combustion engine valves, it is necessary .to first remove the spring normally seating the valve from its operative position so as to permit of the removal of the entire valve. Therefore, my invention is so constructed as to be capable of being quickly and conven-- iently associated with such valve structures and provides means for readily effecting the removal ofthe springs thereof.

A further salient object of the invention resides in a peculiarly formed adjustable cam member, which is arranged to bear upon the valve head and in providing the other extremity of the tool with a removable and adjustable spring elevating leg member, which latter is adapted to encircle the valve stein at a point beneath the` spring seat, so that when said cam is actuated, said leg member will -be elevated to permit of the removal of said spring seat from the valve stem, and to thereby permit of the removal of the valve structure in its entirety.

lWith these and other objects in view, as will appear'asthe description proceeds, the invention consists in the novel features of construction, `combinations of elements and arrangements of parts hereinafter fully described in the following description and set forth with particularity in the appended claim.

In the drawings:

Figure 1 is a vertical longitudinal sec-l type of lifter and .its operative position in connection with the tional view taken through my approved disclosing the same in .views of fthe drawing.

Referring more particularly to the accompanying drawing, there has been diagrammatically represented the valve supporting portions 1 of an explosive engine, the latter being provided, as usual, with a valve structure consisting),` of a head 2 and a stein 3. The lower end of the valve is provided with a `spring seating washer 4, which is held in anormal position by means of the pin 5 passing through the stem, in order that the spring 6 encircling the stem may be operatively held in position, that is to normally maintain rthe head 2 within its seat 6. In removing the valve, it is lfirst necessary to remove the pin 5, which releases the operative connection between the spring 6 and the valve stem 3.A Subsequent to the removal of this pin, the stem itself may 'be also removed from the engine portions 1.

It is the means for permitting the removal of the pin 5` with which my invention is particularly concerned, and to this end use is made of a lifter A, the latter consisting essentially of a yoke 7, fo-rined to provide a cam carrying arm 8 and a spring lifting arm 9, the arms Sand 9 being adjustably connected, as will be hereinafter described, and are preferably formed of U shaped channel iron or of any other suitable material. i

The extremity of the arm 8 is provided with an opening 9', which opening alines with a similar opening formed in a block 10, the latter being integrally formed with the arm S or may be welded thereto, as desired. Inserted through these openings is a cam carrying bolt 11, which is provided with a threaded body for the reception of an adjusting nut 12, the latter having a suitable knurled surface. By rotating the nut 12 the bolt 11 may be adjusted vertically as regards the arm 8, for purpose to be presently disclosed. The lower extremity of the bolt ll is bifurcated to pivotally receive an eccenengagement With the valve 2 by rotating the handle 14. The arm 9 isremovably connected With arm'8 through the provision of a horizontally extending Vtransverse bolt 16, which latter is provided .Withf a1 head 17, adapted to be disposedV Within the channel of the arm 9. The shank of the bolt 16extends through an opening 17, formed in said arm 9, and through an elongatedfy slotl 18 formed in the-lower' end of the arm` 8. A Wear plate 18 encrcles the arm 8 andiis provided with an openingfor the reception of the shank of the bolt 16, and threaded upon the latter is a Wing nut 19, which is adapted to be broughtf intoy frictional engagement with the plate 18 so as toffirmly bind the arms 8 and 9 together. Byloosening th'e nut 19, it will beseenIthat the arms 8andf9=may be adjusted relatively,` and` may be maintained in such adjusted' positions' by the tightening ofthe bolt` 19` into engagement With-theplate 18,` `the elongated slot 18( per'- mitting of the relative movementl between said arms 8 and '9.

The lower end of thearm9 isdisposedvon a horizontal plane and5 terminatesin ai bifurcated end 20, so asto provideastemreceivingl slot 21, Which slot. is` sufficiently large to permit the bifurcated extremity '20 to readily receive the valvefstemB, as shown in Fig; 1. Mypresentzinvention contemplates equipping-.the tool;l A With several sizes of arms 9, so that. the latter may-'be applicable to the various sizes. ofvalve stems.`

In operatiomwhen itL is-desired'to effect the removal of f the valve structure from y the engine 1, the arm-9 isrso'situatedlthat the slot 21 formedtherein Williencircle theY valve stem atf al point immediately beneath the Washer/1, andthe arms Sand 9 are adjusted vertically so that the cam 13-Will engage Withthe upper surfacefof the valve 25. The initialladjustmenty ofthe arms-8 and 9 to effect a proper positioning. of-the camlever asl regards',` the valve 2, iseffected through the bolt and nut connection 17 and 19 existingl between said arms, and ifthis adjustment shouldnot prove to be ample,l affurther adj ustment ofthe camilever may be effected by'rotating the nut 12, so that the vertical position of the bolt 11Y may be readily controlled. The adjustments describedfwill insure a proper position of the lifter Aas regards the valve structure, moreover', by virtue'of the adjustable character ofthe lifter 'fromfitsposition Within the stein 3.

. the ,same can Abe adapted to the different makes ofA explosive engines, this feature having been omitted in my former patent.

After the lifter has been thus positioned, in substantially the manner shown in Fig. 1, the valve may be removed by rotating'the camfleverf 13, S01 that the surface 15 of the latter Will be brought into engagement Awith the upper surface'ofr the valve 2. This operation, due-to theeccentric manner of connecting the lever Withwthe bolt` 11, Willeffect the raising of1 ,the` arms' 8^ and 9,2 to the dotted line position:shown:v in Fig." 1. This permitsthe'wvasher' L L'tobe freed from engagement With'the pin 5, andi' due tothe fact that pressure has been removed from said pin, the latter may bef readily-.Withdimn sequentltothe removal ofthe pin 5, the cam lever is rockedtoits initialiposition, so that the"l samel may be removed from engagment With thevalve'structure' and'to `permitof the removalxof said structure from the engine 1.

From the foregoing description,.taken in connection-With the accompanying drawing, itg Willbe` apparenti that I- have provided a lifter of considerable utility andi one `Wherein a valve may be removed-by ai simple application and Loperationiofthe tool. Through the 'adj ustingfl mechanism described, the field of utility ofthe lifter A vhas been considerably Widened;.sincethe tool' or lifter may be employedi` in. connection with different types and sizesoffexplosiveengines, and is not limited-to'one'particular type, as is the case inmy. former patent;

What: I: claim iszf A= valve lifter for explosive engines, comprising a substantially L shaped frame member; a'loiver' framemember` adjustably and detachablyi carriedv byl said'- former member and provided vvithaslotted valve stemembracing'.k portion, means forelevating and lowering saidy extremity, comprising a threaded rod slidably mounted in' an openingformedin-the freeendof said L shaped member, ainut threadeduponsaidtrod, and a` cam lever pivota'llyl mounted in a slot formed? inrtheloiveri endy of saidl bolt and operable'ivhen oscillated in onedirection to force said. nut in engagementl With-the free end of saidL .shapedfmember' so as toi-effect the. elevationy off said valve stem engaging extremity,.and When'oscillated in a'reverse directionto permit, ofthe lowering of `said extremity.
